The Lord permits no rivals. In Isaiah 43:11, He said, “I, even I, am the LORD; and beside me there is no saviour.” Yet, there is a battle on the horizon that will bring all matters to a head. The Antichrist will sit in the temple of God claiming to be God (2 Thessalonians 2:4). He will torture the people of God (the Jews) and blaspheme the name of God. He will set up his image and demand that the people worship him (Revelation 13:14-15). This peak of idolatry and blasphemy will lead to the culmination of God’s jealousy when He returns to judge the world (Revelation chapter 19).
The Bible consistently identifies the Lord as a jealous God. As the Creator, He deserves man’s undivided allegiance. As the most High God, He is worthy of man’s unadulterated worship. It is often in this vein that the Bible speaks of God’s jealousy. He warned Israel not to make or bow down to any graven images (Exodus 20:4-5; Deuteronomy 5:8-9; Psalm 78:58) because He was a jealous God and would have no choice but to judge such infidelity. The same was true of any false god (Deuteronomy 32:16) or sin (1 Kings 14:22) which man allowed to come between him and his Creator. God is perfectly just in His jealousy since man was created for God’s pleasure (Revelation 4:11).
Historically, the word jealous is connected to the word zeal rather than to envy. Unfortunately, the world has perverted man’s understanding of jealousy by likening it to a detestable sin. The Bible student recognizes that jealousy cannot always be sinful because God says that He is a jealous God (Nahum 1:2) and God does not sin. A scriptural study proves that jealousy can be righteous, or it can be wicked depending upon the intent of the one in whom this jealousy originates. In a very basic sense, jealousy is the unwillingness to share or allow anything to rival the object of one’s desire. Since man has sinful desires, jealously is often viewed as sinful and can lead to other sinful practices. In the Lord’s case, His righteous desire to be man’s only true and living God drives Him to just judgment and godly jealousy.
In Bible times, cities would often build towers to watch the gates to avoid dangers looming from without (Isaiah 21:8). Watchmen would take turns watching the gate. These watchmen were responsible for sounding a trumpet should any danger appear (Ezekiel 33:6). The apostle Paul in his writings applied a spiritual application to this literal act of being a watchman. Just as cities needed men willingly staying awake and alert while others slept or were busy in their daily routines, churches need believers sober and watchful while others might be cumbered about with the cares of this world. Today’s watchmen must use their voices like a trumpet to sound the alarm when danger nears.
